Sandra Peralta went in for HIV testing in March 2016. The results came back positive, according to the Brooklyn Supreme Court suit, but the results of two more rounds of bloodwork were negative. The hospital told Peralta the negative conclusion was “final.”

But then a hospital employee left Peralta a phone message saying she in fact had HIV, the suit says. She was told the same thing when she called the hospital back, it says.

Before discovering once and for all that she was HIV-negative, Peralta underwent “unnecessary medical procedures” and “suffered a loss of marital intimacy,” the suit says. She could not be reached for comment.

“We are not in receipt of a complaint from this patient,” Mount Sinai said.
